In Tiger Bay, the docklands of Cardiff, street urchin Gillie witnesses the brutal murder of a young woman. Instead of reporting the crime, she merely pockets a prize for herself — the perpetrator's shiny black revolver — and flees. When Detective Graham discovers that Gillie has the murder weapon, the fiery young girl weaves a web of lies to throw him off course.
